                  Brief description:

                  The accuracy of Time-difference-of-arrival (TDOA) systems is an important consideration to
                  regulatory authorities and others who have to locate emitters with TDOA-based emitter
                  location systems. To facilitate comparison between TDOA systems, this Recommendation
                  provides guidance on methods of determining the accuracy of TDOA systems, reporting of
                  the results, and selecting the test scenario.

                  Recommendation ITU-R SM.575-3 – “Protection of fixed monitoring stations against
                  interference from nearby or strong transmitters”

       Source:    Brief description:
       WP 1C
                  Strong RF signals may reduce the ability of a monitoring station to receive weak signals and
                  measure them correctly. The protection of radio monitoring stations against strong RF
                  signals is of particular importance in view of the increasing number of antenna sites for
                  mobile and other radio services. Since monitoring stations are often located in urban areas
                  and exposed spots, it becomes more and more difficult to identify suitable new sites and to
                  protect the existing ones.
                  This Recommendation specifies maximum field-strength levels at monitoring stations to
                  ensure their interference-free operation. Its annex describes procedures and calculations
                  for the establishment of protection zones around radio monitoring stations

                  intended to support the material in Recommendation ITU-R P.2040.
                  It is also expected that the material in this Report will be of value in the development of new
                  propagation models.

                  Annex 1 provides information that has been found helpful in planning broadcast and other
                  point-to-area radio services at frequencies below 3 GHz. The contents of this Annex
                  encapsulate measurement data but do not report on a specific measurement campaign.
                  It should be noted that the measurements recorded in this report have been made using a
                  wide variety of methods. In particular, the definition of BEL may differ from that given in
                  Recommendation ITU-R P.2040. Readers are advised to evaluate the material carefully to
                  ensure that it is appropriate for the purpose intended.

                 that it may be displayed on a standard dynamic range (SDR) display device. As the dynamic

                 which the dynamic range is reduced impacts the visual quality that can be achieved. Likewise,

                   This Report contains a summary of the frequency sharing characteristics of digital terrestrial
                   television broadcasting (DTTB) broadcast systems, operating in the frequency range 470-862
                   MHz, required for relevant compatibility studies.
                   It should be noted that for Band I, II, III, IV and V systems broadcasters quote antenna gains
                   and effective radiated power (ERP) relative to a dipole. So, for example, a DTT receiving
                   antenna with a quoted gain of 7 dB has a gain of 9.15 dBi when referenced to an isotropic
                   source. Also, a broadcast station with a quoted ERP of 200 kW (53 dBW) has an e.i.r.p. of
                   85.15 dBm.

                   opportunities to drive user engagement and to maximize the end-user’s satisfaction by offering

                   The process of migration, or “Switchover” from analogue to digital techniques can take many
                   routes, each with its own advantages and disadvantages in terms of rapidity, the players
                   involved, and the degree of government intervention. Often influenced by the local
                   broadcasting legacy, each country will follow its own switchover path. Switchover implies
                   more than a technical migration as the role of TV and radio in modern societies is economic,
                   social and political.

                   and will be updated regularly.
                   Switchover affects all segments in the broadcasting value-chain: from content production
                   through transmission to reception, all of which require technical upgrading to support digital

                  consideration to regulatory authorities and others who must implement monitoring
                  services. It is often difficult to compare different systems due to a number of factors, such

                  requirements, and other issues. To facilitate basic comparisons between different

                  Report ITU-R BT.2470-1 – “Use of Monte Carlo simulation to model interference into DTTB”

                  Brief description:
SG 6
                  Monte Carlo simulation is a statistical method widely used to solve complex mathematical problems, to model physical
                  phenomena or to understand complex real-life problems that cannot be easily modelled by analytical methods. For
                  example, Monte Carlo simulation is used to study collision of atoms, polymer dynamics as well as financial risks.
       Source:    Monte Carlo simulation is based on random sampling to generate a large number of events (experiments), according to the
       WP 6A      model implemented to describe a physical phenomenon. Each generated event, output of the simulation, can be
                  considered as a snapshot in time.
                  Monte Carlo simulation is increasingly being used to assess the compatibility between radio systems. The simulation
                  typically considers randomly distributed sources of interference and randomly distributed or fixed victim receivers.
                  Different system parameters can also be modelled as random variables defined by given probability distributions. Most
                  often, the output of the simulation is processed to calculate the probability of interference to the victim receiver or the loss
                  of data throughput in a network.
                  A deterministic method is used to assess the compatibility between radio systems with a fixed interference configuration.
                  However, it is unable to predict the probability of interference if the interference configuration is not fixed and
                  consequently the risk of interference to the victim system. The merit of Monte Carlo simulation is its ability to create a very
                  high number of possible interference configurations, covering the variability in a system, when assessing the compatibility
                  between radio systems and by doing so assess the risk of interference in a more realistic way compared to a deterministic
                  assessment.
                  This Report expands on Report ITU-R SM.2028 providing further information on how to model interference into DTTB
 Approval date:   services using Monte Carlo simulation. The description and examples presented in this report are based on SEAMCAT, but
